IMPROVEMENT IN GRAIN-SEPARATORS.

Specification forming part of Letters Patent No. 155,404, datedSeptember 29, 1874; application filed October 20, 1873.

To all whom it may concer-n:

Be it known that I, FREDERICK A. BALcH, of Hingham, in the county ofSheboygan and State of Wisconsin, have invented a new and usefulImprovement in Grain-Separators; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, in which- Figure l is a perspectiveview of my machine. Fig. 2 is a vertical longitudinal section of thesame. Fig. 3 is a sectional end elevation of the same.

This improvement relates to that class of separators wherein grains ofdiierent dimensions are separated by means of revolving cylinders havingtheir surfaces indented with cells of suitable size, to receive thesmaller grains and convey them away/,"aud it consists of a method ofsupporting the separator-cylinder by hanging the ends of the same uponrollers placed within said ends, said rollers having bearings in boxesfixed to the frame.

That others may fully understand my iluprovement, I will particularlydescribe it.

I prefer to employ a separator constructed in accordance with my patentgranted August 15, 1871, and numbered 118,094, and for description ofthe general construction and operation of said separator I hereby referto said patent.

A represents the general frame-work to support my machine, though theconstruction and arrangement of the same maybe varied to suit theparticular circumstances or requirements of the place wherein themachine is to be set and operated. B is the cylinder of the separator',constructed with a shell perforated to form cells of the size requiredto receive and carry away the kernels of cockle or very small grain, andsurrounded by a jacket, b, which I iind advisable to make removable, forthe purpose of readily cleaning the cylinder B and its cells. Thecylinder B I mount upon rollers C C upon a shaft, D, which passesthrough said cylinder, and has its bearings in frame A. At the outerends of said shaft are the band-pulleys d cj, the former ot' whichreceives the belt whereby motion is communicated from the prime motor.Small rollers g g are placed upon the frame to steady the motion of thecylinder.

The cockle and very small grain are taken up by the cells in therevolving cylinder, and dropped into the cockle-trough E, which passesthrough said cylinder, and is attached at its ends to the frame-work A.A feedscrew, F, is placed in the bottom of the trough E, to convey thecockle which drops therein to one end, whence it is discharged through aspout, IL, while the wheat is discharged from the end. of cylinder Binto a spout, c', and thereby conveyed to the proper receptacle.

Above the separator B, and-at a convenient distance therefrom, I place ascreening apparatus, constructed to screen out all of the larger kernelsby permitting the smaller ones to pass through said screen, and therebyI not only separate the larger grain and grade it, but the labor of theseparator B is lessened in proportion to the quantity of large grainseparated by said screen.

The revolving screen G is constructed with ble mesh to permit all thecockle and small grain to pass through. This is received in a trough, K,at the bottom of the screen-case, and conveyed to 011e end thereof by ascrew or other suitable conveyer, and discharged through a spout, m,into the separator B, while the larger grain is discharged from the tailend of said screen into a trough, a, and spout, which may discharge itinto spoutz' with the small grain, ,or into a separate receptacle, asmay be required.

The screen-conveyer and revolving screen are operated by belts frompulleys cf.

A hopper or spout, I, may be employed to convey grain to the screen, asmay be most convenient and desirable.

Having described my invention, what I claim as new is- In combinationwith the revolving cockleseparator B, the Han ged roller C upon theshaft D within said separator, to support the same in the mannerdescribed, and cause the same to rotate with unobstructed ends.

FREDERICK BALCH.
